By virtualising the environment in which the software runs, you can collapse the hardware down to a smaller number of servers and run more efficiently. The same logic is now being applied to the radio access network, although there is much more bespoke hardware in a mobile network than a data centre. That's the challenge for small cell manufacturers looking to implement NFV in mobile. Maintaining session continuity across a virtualised network is essential.
